Sealing collet

A sealing collet for use with tools having through holes defined therein for the induction of coolant fluid to the working surfaces of the tool, said collet comprising:

• a plurality of independent gripping jaws longitudinally disposed about a common centerline axis, said gripping jaws having an exposed inner face parallel to the centerline axis and defining an inner diameter for said collet through which the shaft of a machine tool is inserted, said gripping jaws having an angled exposed outer face whereby said plurality of gripping jaws forms a conical outer surface of said collet, each said gripping jaw having at least one hole defined therein whereby all of said holes are circumferentially aligned about said centerline axis;
• a resilient material disposed between said gripping jaws and extending through said holes to form at least one concentric ring through said gripping jaws, said resilient material maintaining said gripping jaws in a predetermined longitudinally and angularly spaced relation about said centerline axis;
• a resilient material outer diameter seal formed integral with said resilient material, said outer diameter seal extending radially outward from said resilient material beyond and across said outer faces of said gripping jaws;
• and
• a resilient material inner diameter seal formed integral with said resilient material and physically separate from said outer diameter seal, said inner diameter seal extending radially inward from said resilient material beyond and across said inner diameter faces of said gripping jaws.
